SPECIFICATION forming part of Letterslatent No. 627,996, dated July 4, 1899.

Application filed September 12,1898. Serial No. 690,757. (No model.)

To a/ZZ whom, t may concern:

Be it known that I, EDGAR' GIROD, a citizen of the United States, residing at Rayville, in the parish of Richland and State of Louisiana, have invented a new and useful Plowg of which the following is a specification. V

My invention lrelates to improvements in plows; and .the Object that I have in view is to improve the means for joining the `share detachably to the moldboard and landside without the employment of bolts, screws, or

rivets and to effect the Wedging of the share irmly in place by the resistance of the soil to the implement.

A further object is toarrange the severa elements in a way to secure a flush joint between the landside, the moldboard, and the share, and also to provide for locking the parts rmly together against tendency to accidental displacement in any direction.

With thes'e ends in View the invention consists in the novel construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to understand the invention, I have illustrated it in the accompanying drawings, forming a part of this specification, and in which- Figure 1 is an inverted or bottom plan view' of a plow having a share constructed in accordance -with my invention. Fig. 2is an elevation looking at the landside of the plow. Fig. 3 is a longitudinal sectional elevation on the plane indicated by the dotted line 3 3 of Fig. 1. Fig. 4 is a detail horizontal sec-tion through the landside and the sole-fiange of the share, the plane of section being indicated by the dotted line l 4 of Fig. 2. Fig. 5 is a perspective View of the share detached from the moldboard and landside. Fig. 6 is a detail perspective view of a part of the landside and standard to show the crotch or seat for the reception of the sole-flange on the share.

Like numerals of reference denote like and .corresponding parts in each of the several united in any way approved by those skilled in the art. The landside 13 is arranged to Overlap the lower part of the stock, and this landside is peculiarly constructed, as willA presently appear, andis united to the pointed end 11 of the stock to form therewith a crotcch or seat, as shown by Fig. 6. The handles let of the implement are tied together and united to the beam in a manner well understood by those skilled in the art, and the lower end of one handle is attached, as at Y15, to the heel of the landside, while the corresponding end of the other handle is united to a lug' 16 on the lrear neutral face of the moldboard.

The front extremity of the landside 13 is formed with a downward and rearward sloping edge 17, and this sloping `edge is beveled inwardly toward the pointed extremity 11 of the stock.

The share 2O is cast in a single piece, with a sole-flange 23, that protrudes beyond the rear edge of the share, which is designed to underlap the lower edge of the moldboard and produce a flush joint between the share and the moldboard. `fAs is usual in the art, the share has a point 2l and the front cutting edge 22; but in lieu of making the point integral with the share, as hereinshown, I may employ a separable or detachable point, which, however, I do not deem it necessary to illus# trate. The sole-flange 23 of the share, which projects beyond the rear edge thereof, is arranged to overlap the pointed end l1 of the stock, and the projecting end of the sole- `flange is peculiarly fashioned to tit snugly to the end of the landside, so that the sole-dange and the landside may interlock, and the faces and edges thereof will lie flush to avoid any protruding parts at the joint between the landside and the share. To attain this end, I forni the projecting rear extremity of the sole-iiange 23 with a sloping edge 24, that inclines downwardly and rearwardly at an angle corresponding to the edge 17 of the landside, and this sloping edge 24:- of the soleilange is beveled inwardly to correspond with the bevel 18 of the landside. It will thus be observed that the share has its sole-flange constructed to overlap the pointed end of the stock and to underlap the sloping and beveled edge of the landside when the share is properly fitted to the moldboard and stock, and

IOO

the face, aswell as the edge, of the sole-flange lies flush to the corresponding parts of the landside.

On the under neutral face of the share are cast the spaced lugs 25,- having the beveled edges, 25, and these lugs are spaced to form between their beveled edges a tapered keyseat 26. To lock the share to the moldboard, I resort to the employment of a tapering key or wedge 27, which is arranged to fit snugly against the curved rear face of the moldboard and is provided with a longitudinal slot 29, through which passes the bolts 30, that are rigid with the mold board. The key or Wedge is held on the under side of the moldboard by the nuts 31, which are screwed on the bolt to'bear against the key, and the tapered working` end of this key or Wedge protrudes beyond thelower edge of the moldboard, so as to fit intothe key-seat formed by and between the beveled edges of the lugs on the share. The heel of this key or wedge has an offstanding flange 28, which provides a convenient means by which the key may be adjusted.

To remove the share from the plow, the key or wedge is driven out of the key-seat in the share, and the latter is then Withdrawn from the `moldboard, so as to disengage its soleflange from the crotch or seat at thejuncture of the landside and stock. To replace the pointed share, it is adjusted for its rear edge to nnderlap` the moldboard and to have the sloping and beveled heel of its sole-flange enter the crotch or seat of the landside and stock, so that the heel of said sole-fiange will overlap the pointed end of the stock and will underlap the sloping and beveled front` extrem# ity of the landside, after which the wedge or in construction, to the end that the share may bel cast in a single piece and the parts readily assembled together without finishing the same by hand. The share may be easily detached having their opposing edges beveled and formv ing a dovetailed Way, a moldboard, a slotted endwise-movable key curved to conform to the moldboard and fitted thereto in alinement with the dovetailed way for adjustment into engagement with the lugs, and bolts fixed to the moldboard and fitting inthe slots of the.

key to slidably hold the latter in place, substantially as described.

2. The combination, in a plow, with amoldboard and a stock, of the landside provided with a sloping and beveled front extremity which laps the stock and forms therewith a seat or crotch, a share having its sole-flange provided with the sloping and beveled heel which is fitted snugly to thesloping and beveled edge, of the landside, for the sole-flange to lie Hush with the face of said landsid'e, and means for fastening the share to the moldboard, substantially as described.

3. In a plow, the combination with a moldboard, and a stock having a pointed extremity, of the landside having the inclined and beveled extremity which is arranged to overlap the stock, a share having its sole-fiange formed with a sloping and beveled heel and fitted to the end of the landside for the faces of the sole-iiange and the landside to lieiiush with'each other, the beveled lugs on the rear face of the share, and a key or wedge slidably confined on the moldboard and engaging with said lugs, for the purposes described, substantially as set forth. v

In testimony that I claim the foregoing as my own I have hereto affixed my signaturein the presence of two witnesses.
